PIA formula For an individual who first becomes eligible for old-age insurance benefits or disability insurance benefits in 2020, or who dies in 2020 before becoming eligible for benefits, his/her PIA will be the sum of: (a) 90 percent of the first $960 of his/her average indexed monthly earnings, plus (b) 32 percent of his/her average indexed monthly earnings over $960 and through $5,785, plus (c) 15 percent of his/her average indexed monthly earnings over $5,785. We round this amount to the next lower multiple of $.10 if it is not already a multiple of $.10.
